l ENGINE.

Application led August 24, 1926. Serial No. 131,253.

This invention relates to engines and more particularly to improved ower transmitting mechanism, an object of t e invention being to provide an engine with a iywheel containing a countershaft directly geared to the crank shaft of the engine, so that vibration is minimized and other advantages had; A further object is to provide improvements 0f this character which can be connected to any engine in ordinary' use without altering the engine.

With these and other objects in view, -the invention consist incertain novel features of constructionand combinations and arrangements of parts, which will be more fully hlereinafter described and pointed out in the c alm.

' t -In the accompanying drawings- Figure 1 is a view, partly in elevation and f partly ,in section, illustrating my invention 'as applied to an engine of the four-cylinder e ut it is ofcourse to be understood t at the invention may be employed with angltype of engine;

'gure 2 is a view 1n transverse section on the line 2-2 of Figure 1.

1 represents an engine of the internal combustion type, although it is to be understood that the invention may apply to any type of engine. 2 is the crank shaft which is connected by pitmen or connecting rods .3 with the several pistons (not shown).

This shaft 2 is mounted in bearings 4 and turns in a crank case 5. 6 represents my improved countershaft which is supported in bearingbeblocks 7, the latter being secured to the arings 4 so as to rovide a rigid mountingfor the oountersha On the crank shaft 2 at both ends thereof gear wheels 8 are secured and mesh with smaller gear wheels 9 on thecountershaft 6 so as to drive the latter at an increased speed over that of the crank shaft 2. 10 represents a iywheel which is secured on the countershaft 6 and not on the crank shaft, as is customar in the art.

It is this road idea of a.countershaft carrying a Vlywheeland geared directly to the crank shaft of an engine which constitutes the broad idea of my invention, and I do not wish to be limited to the specific details of 'construction but desire to cover broadly the idea as expressed as Iv am fully convinced that such a construction gives vastly improved results over engines such as ordinarily made. i

Various changes and alterations might be made in the general form of the parts described without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

I claim:

In combination with an engine having a crank shaft and bearings for the crank shaft, of bearing blocks secured to the last mentioned bearings, a countershaft insaid bear: ing blocks, gears connecting the crank shaft .and the countershaft, and a flywheel on the countershaft.

ARTHUR, CORONA.
